Netty Sctp Heartbeat在错误的界面上

标签： connection netty reset heartbeat sctp

我在两台不同的机器之间使用与Netty的NioSctpServerChannel连接。在客户端的channelActive-Handler将一些数据发送到服务器之后，连接成功建立并接收数据。

接收接口似乎不是绑定接口（192.168.122.1而不是192.168.243.31） - 这是系统还是网络问题？

然后通过完全不同的接口（在这种情况下为virbr 192.168.122.1）发送心跳，并通过中止来解除心跳，从而破坏连接。当客户端尝试发送心跳时，从逻辑上讲，由于连接已经关闭，因此中止也会中止。

PC1 192.168.243.31（服务器） PC2 192.168.243.12（客户）

服务器初始化代码：

public void run() throws Exception {
    EventLoopGroup bossGroup = new NioEventLoopGroup(1);
    EventLoopGroup workerGroup = new NioEventLoopGroup();
    try {
        ServerBootstrap b = new ServerBootstrap();
        b.group(bossGroup, workerGroup)
                .channel(NioSctpServerChannel.class)
                .option(ChannelOption.SO_BACKLOG, 100)
                .handler(new LoggingHandler(LogLevel.INFO))
                .option(ChannelOption.SO_KEEPALIVE, true)
                .childHandler(new ChannelInitializer<SctpChannel>() {
                    @Override
                    public void initChannel(SctpChannel ch) throws Exception {
                        ch.pipeline().addLast(new Handler1());
                        ch.pipeline().addLast(new Handler2());
                        ch.pipeline().addLast(new Handler3());
                    }
                });

        System.out.println("Connector binding...");
        ChannelFuture f = b.bind("192.168.243.31", port).sync();
        f.channel().closeFuture().sync();
    } finally {
        bossGroup.shutdownGracefully();
        workerGroup.shutdownGracefully();
    }
    System.out.println("Connector ended.");
}

日志输出：

我解决了这个问题：

客户端必须绑定到特定的IP地址。否则，所有接口地址都在sctp内发送。如果每次重合都有相同的接口IP地址:-(心跳传输到您自己的接口......
